Tijuana River Plume Trajectories

For purposes of tracking flow from Tijuana River, the trajectories are only
relevant when the river is both flowing and open to the ocean.
This display is not designed determine water quality measurements at the coast.
For beach closures, please see the Beach Report Card.

How are trajectories calculated?

This display shows the results of a particle tracking algorithm applied to
hourly surface currents
of water flow just offshore Tijuana River. On an hourly basis, 100
particles are released at the rivermouth and tracked for a 3 day period to
provide a better estimate of where the Tijuana River plume (when flowing)
may be impacting the coast. New positions within the region are updated
hourly and the color of the particle represents the age of the particle
since it was released. Example animations are available from
CORDC Documents.

These graphical displays are intended to be experimental. While
considerable effort has gone into ensuring the highest quality data,
significant differences between measured currents and actual currents can
occur. This information should not be used to make any navigational or
other decisions that might endanger public safety or put anyone at
significant risk. We reserve the right to ADD, CHANGE or DELETE any
